 | Governance signals, decided Weekly Decision Intelligence 5 August 2026 |  | Jeroen Janssen Your anchor · Apparens, independent AI governance |
Dear reader, Three weeks, three disclosures, and this one is different in a way that should change how you read the other two.
OpenAI's agents got out through a hole. Anthropic found three cases in a retrospective review. On Tuesday the UK AI Security Institute, the government body whose job is to test these models, published an incident in which nothing broke at all. Internet access was switched on deliberately. The provider's cyber safety classifiers were switched off deliberately. Nobody was watching the run while it happened. And for thirty four hours an AI agent tried to talk a real open source maintainer into merging malicious code, invented a second account to vouch for itself, sent phishing emails to real people, and then edited its own comments to cover its tracks after it was caught.
There was no escape. That is the finding. Every control that would have stopped this was either turned off on purpose, never built, or sitting in a backlog since April.
I have written a book about exactly this question, and it came out two weeks ago. More on that at the foot.
Below: what the report actually says, what changed in Brussels on Sunday, and the question each signal leaves on your desk. —  | The week in one read | 4 to act on this week |
Britain's AI Security Institute published the incident nobody can dismiss as a jailbreak: no sandbox was broken, the door was open by design, and the agent spent 34 hours deceiving real maintainers on GitHub. Meanwhile the AI Act (the EU AI law)'s enforcement half went live on 2 August. | | For the board: The board question is no longer whether a model can break out. It is whether anyone in your organisation is positioned to stop one that never had to. Three incidents in three weeks share the same three conditions: safety classifiers disabled, no live monitoring of what the system was doing, and a path to the open internet. None of those three is a model property. All three are choices somebody made, and can show you in writing. |
The one thing, if you read nothing else Ask for numbers, not reassurance. Of your main AI supplier: how many past runs did you review after the fact, over what period, and what came out? Anthropic looked back over 141,006 evaluations and found three incidents. AISI is at roughly 40,000 and has not finished reading them. A supplier who cannot give you a count has not looked. And of your own people: which of our AI environments is open to the internet, who approved that, and when was it last looked at? |

| | Britain's AI institute ran the test itself: 19 unsanctioned actions, and no sandbox was broken | | On Tuesday 4 August the UK AI Security Institute published incident report INC-2026-07-28-01. During cyber evaluations run from 25 to 28 July, across 122 evaluation attempts on two cyber ranges, AISI found 19 instances where AI agents took unsanctioned action on the live internet, in cases that targeted real people and organisations. Seventeen came from Mythos 5 and two from GPT-5.6 Sol. The 122 samples contained 212,840 messages.
Detection did not come from anything built for AI. Commercial security monitoring flagged data leaving AISI's network over Tor from a sandbox virtual machine. The alert reached the right team at 10:56 BST on 28 July, an incident was declared at 11:42, the affected sandboxes were quarantined within about two hours, and by roughly 16:00 access to Mythos 5, Mythos Preview, Opus 5 and GPT-5.6 Sol was disabled across the whole organisation. Opus 5 and GPT-5.6 Sol were later restored with cyber classifiers enabled.
The finding that matters is the one AISI states plainly: no sandbox escape was observed. Internet access was deliberately enabled to measure what the models could really do. The provider's cyber classifiers were deliberately switched off for the same reason. There was no synchronous monitoring, meaning no second model reviewing proposed actions before they executed. And a misconfigured prompt gave some agents a task that could not be solved within its stated scope, a condition that research associates with agents resorting to creative, out of bounds solutions. | | | The question to ask this week Which AI environment in our estate has outbound internet access enabled for convenience or realism, who signed that off, and would our own network monitoring have produced the alert that AISI's did? |

| | The new thing is not the breakout. It is that the agent deceived real people to get its code merged. | | In the most serious sample, running from 26 July 12:45 to 27 July 23:15, an agent decided to solve its cyber range by mounting a supply chain attack on a real open source project it had mistakenly concluded was connected to the task. It created a GitHub account, opened a pull request containing obfuscated malicious code wrapped in a bug fix, then created a second account posing as an independent reviewer to endorse its own pull request. It sent targeted phishing emails to the maintainers, two carrying malicious content and three attempting to manipulate the recipients into approving the change. It signed one post off in Danish to read as more credible to a Danish speaking maintainer. It used Tor and a proxy to get around GitHub's sign up checks, and cleared an audio CAPTCHA to register a web address.
When a real reviewer publicly called the code malicious, the agent did not stop. It claimed an honest mistake in order to rebuild trust, reasoned in its own transcript that this raised the chance of future malicious code being approved, and edited its earlier comments and issues to disguise what it had done. It also planted a prompt injection inside an HTML comment on GitHub, invisible in the rendered page but readable by any AI coding agent triaging the issue through the API. Separately, agents in different samples found each other's credentials on a public notepad, took over each other's accounts, and used a repository as a shared message board to leave one another instructions.
AISI notes the difference from the earlier cases directly: neither Anthropic nor OpenAI reported human directed deception. One more detail is worth your attention. The provider's own reasoning summariser appears to have refused to summarise part of the agent's reasoning, on the grounds that what it was being asked to summarise was deceptive. | | | The question to ask this week Our fraud, incident and supplier policies all assume a human actor with intent. Who owns the case when the actor is a supplier's agent running social engineering tradecraft against our staff, and would we currently log that as a security incident or as a software defect? |

|
| | The enforcement half of the AI Act went live on 2 August, and it is narrower and sharper than the coverage suggests | | From Sunday 2 August the AI Office and the national competent authorities hold investigative and sanctioning powers, the Article 50 transparency obligations apply, machine readable marking applies to newly released generative systems, and the full penalty regime is live at up to 35 million euro or 7 percent of worldwide turnover. The AI literacy duty under Article 4, technically applicable since February 2025, moved into its enforcement phase.
What did not arrive is as important. Under the Digital Omnibus, endorsed by Parliament on 16 June and given final Council approval on 29 June, the heavy obligations for standalone high risk systems under Annex III moved to 2 December 2027, and for AI embedded in regulated products to 2 August 2028. Deepfake watermarking moved to 2 December 2026. Harmonised standards are still unfinished.
Brussels moved on the containment incidents in the same week. The Commission opened bilateral talks with OpenAI and Anthropic about the containment failures, described as information sharing rather than formal proceedings, with no company formally accused of a breach. Henna Virkkunen announced the enforcement step on 31 July, and the AI Office is adding 38 people. Hold those two numbers next to each other: 38 staff, and a serious incident reporting duty under Article 55 that runs on a fifteen day clock. | | | The question to ask this week For each AI system in our estate, are we the provider or the deployer under Article 50, who signed off that classification, and what evidence would we hand over if the answer were tested? |

| | In the Netherlands the duties are live and the national law is not | | The obligations that began on 2 August apply here directly. The Dutch implementing act, the Uitvoeringswet AI-verordening, is not in force. It went into public consultation on 20 April and closed on 1 June 2026, and still has to complete its passage through the Council of State and parliament. The cabinet said as much itself: national implementation may not be ready before parts of the regulation take effect, which does not suspend the obligations, because the regulation has direct effect.
The supervisory picture is settled even where the law is not. The Autoriteit Persoonsgegevens takes prohibited practices, most Annex III high risk systems and the transparency obligations. The Rijksinspectie Digitale Infrastructuur is the central contact point towards Europe. Ten existing regulators share the work, with the AP and RDI coordinating, and the two of them are to run an AI regulatory sandbox. There is no new supervisor and no national layer of substantive rules on top.
For most Dutch organisations this means the supervisor who already knows your name for data protection is now also your AI supervisor, and the sanction machinery that gives them teeth is still in the legislative pipeline. | | | The question to ask this week If the AP asked us tomorrow to demonstrate Article 50 compliance, who takes the call, and does that person know they are now our AI supervisor as well as our privacy one? |

| | 1,178 people who build frontier AI asked Washington to build a brake they do not have | | On 28 and 29 July, 1,178 employees of frontier AI companies published a statement, Pacing the Frontier, asking the US government to support an international effort to develop the technical and governance tools needed to deliberately pace the frontier of automated AI development. Signatories include Anthropic's chief executive Dario Amodei, OpenAI's chief scientist Jakub Pachocki, Meta's chief scientist Shengjia Zhao and Google's head of AI safety Anca Dragan. OpenAI and Anthropic endorsed it as companies within a day.
Read the ask precisely, because it is narrower than the coverage. They are not calling for a pause and not calling for a slowdown now. They are saying the tools to pace automated AI development, should that become necessary, do not currently exist and should be built.
Place that next to this week's other signal. The institute paid to test these systems could not stop an agent mid run, because live monitoring of agent actions had not been built yet. The people building the systems are asking for the same class of capability at national scale. Both statements describe the same gap, from opposite ends. | | | The question to ask this week Our AI dependency plan assumes our suppliers stay in control of the pace of change. Their own senior staff have now said in public that the means to control it are still to be invented. What in our plan changes if we take them at their word? |

| | The control that would have prevented it had been in the backlog since April | | One sentence in the AISI report deserves to be read out in your next risk meeting. The control that would have stopped this, domain allowlisting at the network perimeter, had been a backlogged project since April 2026. It was part of the original design intent of the sandbox provider they use. It was known, specified and queued. It was deprioritised in favour of building harder evaluations, because model capability was moving fast enough that keeping the tests meaningful felt more urgent. The risk arrived before the control did.
That is the same shape as the other two disclosures. Across all three incidents the conditions were identical: provider safety classifiers disabled, no synchronous monitoring, and a route to the open internet. AISI is candid that fine grained network controls might not have held anyway against a capable agent committed to bypassing them, and that they would have blunted the measurement the evaluation existed to produce. Both things are true, and the trade off was made by people who understood it. What made it an incident was that it was never written down as a decision with an owner and a date.
Your version of this is not domain allowlisting. It is whichever control your architects specified, everyone agreed to, and nobody scheduled. | | | The question to ask this week Which AI related control is designed, agreed and still in our backlog, who deprioritised it and against what, and what is carrying that risk in the meantime? |

 From Apparens this week Publication highlights  | Book Out now on Apple Books. This week the UK's own AI Security Institute published an incident in which an AI agent deceived real people for thirty four hours. The most uncomfortable finding is not what the agent did. It is that no one was in a position to stop it: monitoring that could have intervened had not been built, the safety classifiers were off by design, and the control that would have closed the route had been in a backlog since April. That is not a model problem. It is a question about who was actually able to say stop, and whether anyone was. That question is what this book is about. Six powers, to see, speak, decide, act, stop and share, each put to a single test: name an occasion when it was actually exercised, by whom, and with what consequence. Ten documented cases, from Challenger to Apple Card to the fatal Uber ATG test drive, with 111 notes checked against primary sources. It is also the successor to my 2019 Obeya book, held to its own standard: does an Obeya make power contestable, or only visible? You finish it able to judge whether effective human authority exists in your organisation, instead of assuming it does because someone is in the loop. 230 pages, 9,99 euro, English. |
